[jira] [Created] (KAFKA-20450) SafeObjectInputStream uses denylist based approach

Subbu created KAFKA-20450:
-----------------------------

             Summary: SafeObjectInputStream uses denylist based approach
                 Key: KAFKA-20450
                 URL: https://issues.apache.org/jira/browse/KAFKA-20450
             Project: Kafka
          Issue Type: Bug
            Reporter: Subbu


File : connect/runtime/src/main/java/org/apache/kafka/connect/util/SafeObjectInputStream.java 



The current SafeObjectInputStream uses a denylist based approach - having a fixed denylist to be validated against for deserialization. This is a bad security practise and has also been mentioned in the original PR.

We need to use allowlisting as a better security practise.
